ELMER E. GRAFFTEY, OF KANSAS CITY. MISSOURI.

CLEANSER.

Application filed March 10, 1916. Serial No. 83,419.

To all whom it may concern:

Be it known that I, ELMER E. GRAFFTEY, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in Cleansers, of whichthe following is a specification.

My invention relates to brushes of that type in which the bristles orfibers are re movably held in a hollow brush head, so that when worn outthey can be readily replaced with others.

An important feature of the present invention resides in a tubular tuftholder having ports communicating with the interior of the hollow brushhead, so that a cleansing fluid therein may flow out through the portsand thus keep the bristles or fibers constituting the tufts clean and ina sanitary condition.

While adaptable to a large variety of uses, my brush is particularlyadapted for use in packing houses for cleansing carcasses, and theinterior of cans before the same are filled with food products, andsince the brush is self-cleansing the tufts need not be discarded onsanitary grounds until worn out.

Other features of the invention will hereinafter appear, and in orderthat said invention may be fully understood, reference will now be madeto the accompanying drawing, in which:

Figure 1 is a longitudinal section of a brush made in accordance with myinvention. Fig. 2 is a cross section on line 11-11 of Fig. 1. Fig. 3 isa detail perspective view, enlarged, of a tubular member forming animportant feature of the invention. Fig. 4 is a vertical section of thetubular member. Fig. 5 is a section of a modified form of brush with thetubular members formed integral with the brush head.

Referring now to the drawing, in which similar reference numeralscorrespond with similar parts throughout the several views:

. 1 designates the brush head which may be of either wood, metal, orother suitable material, and is, preferably, of hollow construction toprovide a chamber for holding steam, or other cleansing agents, such,for instance, as water, liquid soap, etc.

The steam or liquid is supplied to the hollow head 1 through a coupling2, to which Patented J an. 30, 1917.

the hollow head is filled therewith and the coupling 2 is then closedwith a cap 3. I

4 designates a socket fixed to the top of the head 1 and adapted toreceive a handle 5, whereby the brush may be conveniently manipulated.

6 designates a plurality of tubular members in which the bristles orfibers 7 are reliably secured by Wires or other suitable elements 8, sothat when worn out said bristles can be readily replaced with others.

Each tubular member 6 has screw threads 9 at its lower portion adaptedto be screwed into correspondingly threaded apertures in the bottom ofthe brush head. Peripheral shoulders 10 at the lower ends of the members6 are provided to abut the lower surface of the bottom of the brush andthus limit the entrance of the members 6 therein. The upper portion 11of each element 6 is of truncated conical form and has two op positelydisposed openings 12 and a top opening 12"-, through which itsrespective Wire 3 is threaded and through which steam or liquid may flowfrom the hollow brush head. The lower portion of each element 6, alsohas oppositely disposed ports 13 through which steam or liquid in thehollow head 1 discharges and freely flows around the bristles 7, keepingthe same free of foreign matter and in a clean and throroughly sanitarycondition during the operation of washing any surface over which saidbristles may be rubbed. The truncated upper portion 11 of the element 6forms an abutment for the upper end of its respective tuft and not onlyrelieves the retaining wire 8 of all strain, but prevents the fibersbeing cut on said wire as would be the case if the latter had towithstand the upward pressure of said tuft while the same is beingforced over a surface to be cleaned.

The tubular members 6 are made of any suitable material and any desirednumber may be employed, and while I have shown them applied to a hollowrectangular brush head, it is to be understood that they may beconnected to any desired form of head whether it be chambered or solid.

In the modified form disclosed by Fig. 5, the tubular members 6 areformed integral with the bottom of the hollow head 1*, which has aremovable top 1", so that access may be had to the wires when the tuftsare to be secured in, or removed from said members 6.

having a shoulder at its opposite end surmounted by screw threads portsin said tubular member, means for securing the tuft in said tubularmember, and a brush head into which the tubular member is adapted to bescrewed.

In testimony whereof I affiX my signature, 20
